Debugging Vim plugins written in RubyEdit

Created , updated

If your plug-in raises a Ruby error from inside a ruby eval during initial execution you won’t see the exception, nor can you rescue it and print it via VIM::command "echo #{exception}".

The only solution seems to be writing it to a file:

begin
  # ...
rescue Exception => e
  File.open("/tmp/exception_info", 'a') { |f| f.puts "#{Time.now}: #{e}" }
end
